pipenv安装库使用国内镜像 pip使用国内镜像解决安装超时

pipenv install django超级慢，卡住不动，最后不得不CTRL+C中止

这时有必要改成国内源了，打开Pipfile文件，发现内容是：

[[source]]
verify_ssl = true
name = "pypi"
url = "https://pypi.org/simple"

[packages]


[dev-packages]

[requires]
python_version = "3.4"

把url替换成阿里云源(这里国内源的选择问题可以参考我上篇文章：《pip使用国内镜像解决安装超时》)：http://mirrors.aliyun.com/pypi/simple/     

运行发现有出现不信任的问题了

索性将url改成url = "http://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com"

[[source]]
verify_ssl = true
name = "pypi"
url = "http://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com"

[packages]


[dev-packages]

[requires]
python_version = "3.4"

再次安装，显示：

这个问题是由于django需要python版本大于等于3.5，我的是3.4.4，版本不匹配导致，换requests库试试：pipenv install requests

可以看到，只花了3s，速度感人，有人说，清华源更好用，豆瓣源不好用，还没尝试

需要注意的是，这时候Profile文件中的[packages]下，多了requests = "*"，标识了本项目依赖于requests

[[source]]
verify_ssl = true
name = "pypi"
url = "http://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com"

[packages]
requests = "*"

[dev-packages]

[requires]
python_version = "3.4"

同时安装过程中有句话叫做 Updated Pipfile.lock，这时我们可以发现项目路径下又生成了一个 Pipfile.lock 文件，内容如下：

            "sha256": "2520a3c6b3ead035956ec3f7f1a9ebeb0c274f4e1568f752dcfd4d6538193c52"

            "version": "==1.23"
        }
    },
    "develop": {}
}

可以看到里面标识了 Python 环境基本信息，以及依赖包的版本及 hashes 值
